Antonio Tirol Carpio (Tagalog pronunciation: [anˈtɔnjo ˈkaɾpjo]; born October 26, 1949) is a former associate justice of the Supreme Court of the Philippines. He was sworn in as a member of the Supreme Court by President Gloria Macapagal Arroyo on October 26, 2001, and served until his retirement on October 26, 2019. He served as associate justice of the Supreme Court of the Philippines for a period of eighteen years. He also served as chief justice in an acting capacity several times during his tenure as Senior Associate Justice.
Antonio Carpio was born in Davao City to Bernardo Dumlao Carpio and Sol Gonzales Tirol. He completed his elementary and secondary education at the Ateneo de Davao University. He then attended the Ateneo de Manila University, graduating with an undergraduate degree in economics in 1970. He earned his law degree from the University of the Philippines College of Law at UP Diliman, where he graduated valedictorian and cum laude in 1975. Carpio is married to Ruth Nguyen Carpio.
During his time at the University of the Philippines, Carpio served as the chairman of the editorial board for the Philippine Law Journal, editor-in-chief of The Guidon, and managing editor of the Philippine Collegian. He placed sixth in the 1975 Philippine Bar Examination with a rating of 85.70%.
Following his admission to the bar, Carpio entered private legal practice. In 1980, he co-founded the Carpio Villaraza Cruz law offices—frequently referred to in Philippine legal circles as "The Firm," in reference to the John Grisham novel. Alongside his private practice, he taught tax law, corporate law, and negotiable instruments law at the University of the Philippines College of Law from 1983 to 1992. He also served as a member of the university's Board of Regents from 1993 to 1998.
In 1992, Carpio joined the administration of President Fidel Ramos as Chief Presidential Legal Counsel. In this capacity, he worked on regulatory reforms within the telecommunications, shipping, civil aviation, and insurance industries. Following the end of the Ramos administration, Carpio returned to private practice during the presidency of Joseph Estrada and wrote a regular opinion column for the Philippine Daily Inquirer.
In January 2001, Carpio became the first appointee of President Gloria Macapagal Arroyo to the Supreme Court of the Philippines. Appointed at the age of 52, he was one of the youngest associate justices in the court's history.
During his 18-year tenure on the High Tribunal, Carpio chaired the court's Second Division, headed the Committee on the Revision of the Rules of Court, and served as the chair of the Senate Electoral Tribunal. He retired from the judiciary on October 26, 2019, declining a traditional en banc special retirement session, opting instead for a private retirement dinner.
Periods as Acting Chief Justice
Carpio served as the Acting Chief Justice of the Supreme Court on two major occasions. He first assumed the post on May 29, 2012, following the impeachment and removal of Renato Corona. As the most senior associate justice, contemporary commentators noted that legal tradition favored his permanent appointment to the position. However, President Benigno Aquino III ultimately selected Associate Justice Maria Lourdes Sereno. Carpio assumed the acting role a second time on March 1, 2018, after Sereno took an indefinite leave of absence during her own subsequent removal proceedings.
In total, Carpio accumulated eight months of service as acting chief justice, longer than any other senior associate justice in the court's history.
Throughout his tenure, Carpio was considered for the position of Chief Justice five times by the Judicial and Bar Council, but never attained the permanent post:
2010: He declined the nomination to succeed Reynato Puno, citing delicadeza regarding midnight appointments made by an outgoing administration.
2012: Following Corona's ouster, he was considered, but President Aquino ultimately appointed Sereno.
2018 (May): Following the ouster of Sereno, Carpio declined his automatic nomination, having dissented from the decision on the grounds that the court did not possess the constitutional authority to oust its own members via quo warranto.
2018 (October): Following the retirement of Teresita de Castro, Carpio accepted his nomination; however, President Rodrigo Duterte chose Associate Justice Lucas Bersamin.
2019: Prior to his compulsory retirement, Carpio declined his final automatic nomination, stating he did not wish to hold the title for only a matter of days.
Lauro Vizconde disbarment complaint
In 2012, the Supreme Court dismissed a disbarment complaint filed against Carpio by Lauro Vizconde. The complaint had alleged inappropriate influence relating to judicial appointments dating back to Carpio's time as chief presidential legal counsel in 1992.
